摘要： An air removal mechanism includes a body having a hollow portion capable of storing a liquid. In a state where the body is mounted on an introducer sheath, a medical device to be inserted into the introducer sheath is insertable via the hollow portion. The body has an injection path which communicates with the hollow portion and on which an outlet is open toward a valve body.
